Answer:
-30r+15
Step-by-step explanation:
Apply the distributive law:
20(-1.5r)+20 · 0.75
Apply minus plus rules:
-20 · 1.5r +20 · 0.75
Simplify:
-20 · 1.5r + 20 · 0.75 = -30r+15

The area of a square shaped yard is 201.5 ft2. Which measurement is closest to the side length of this yard in feet?
Answer:
a = 14.19 feet
Step-by-step explanation:
Given that,
The area of a square shaped yard is 201.5 ft²
We need to find the side length of this yard in feet.
The area of a square shaped object is given by :
A = a², a is the side length of the object
Put A = 201.5 ft² in above formula,
[tex]201.5=a^2\\\\a=\sqrt{201.5 } \\\\a=14.19\ \text{feet}[/tex]
So, the side of the square yard is 14.19 feet.
what is the greatest common factor shared by 10 and 40
[tex]\huge\bold\green{Answer:-}[/tex]
Greatest common factor (GCF) of 10 and 40 is 10.
GCF(10,40) = 10
[tex]\huge\bold\red{Explanation:-}[/tex]
We will now calculate the prime factors of 10 and 40, than find the greatest common factor (greatest common divisor (gcd)) of the numbers by matching the biggest common factor of 10 and 40.
Prime Factorization of 10
Prime factors of 10 are 2, 5. Prime factorization of 10 in exponential form is:
10 = 2¹ × 5¹
Prime Factorization of 40
Prime factors of 40 are 2, 5. Prime factorization of 40 in exponential form is:
40 = 2³× 5¹
Factors of 10

Factors of 40
List of positive integer factors of 40 that divides 10 without a remainder.
1, 2, 4, 5, 8, 10, 20
Greatest Common Factor
We found the factors and prime factorization of 10 and 40. The biggest common factor number is the GCF number.
So the greatest common factor 10 and 40 is 10.
The Greatest Common Factor of 10 and 40 is 5.
What is Greatest Common Factor?The greatest common factor is the largest number that is a factor of two or more numbers (GCF). The greatest number (factor) divides them, yielding a Natural number. Once all of the number's variables have been identified, there are a handful that are shared by both. The greatest common factor is the largest number found among the common factors. The GCF is often referred to as the Highest Common Factor (HCF)
For example, 12, 20, and 24 have two common factors: 2 and 4. The largest is 4, so we say that the GCF of 12, 20, and 24 is 4.
Given:
We have to find the greatest common factor of 10 and 40.
So factorizing each number
10 = 2 x 5
40 = 2 x 2 x 2 x 5
Here the common factor of 10 and 40 is
= 2 x 5
= 10
Thus, the Greatest Common Factor is 10.

Four brothers each bought two hot dogs and a bag of chips at the football concession stand. If the bag of chips was $1.25, and the total was $18.20, what was the price of one hot dog
Your answer is 1.65.
(may have a hard time explaining it)
SO, there are 8 hotdogs and 4 bags of chips, 4 times 1.25 is 5, and 18.20 minus 5 is 13.20, so the chips are out of the equation. Now all we must do is divide what's left (13.20) by 8:
13.20/8=1.65

x−y=−8 in slope intercept form
Answer:
-y=-x+-8
Step-by-step explanation:
Answer:
y = x + 8
Step-by-step explanation:
Slope-intercept form looks like y = mx + b.
We have X−y=−8 and need to solve this for y:
Change all signs, obtaining -x + y = 8
Add x to both sides, obtaining y = x + 8
Solve the equation for x.
x2 = 9
= 2x = 9
= x = 9 ÷ 2 ( transposing ×2 from LHS to RHS changes ×2 to ÷2 )
= x = 4.5
Therefore , x = 4.5 .

Qd=240-5P
Qs =P
Where qd is the quantity demanded, qs is the quantity supplied and p is the price. Determine the equilibrium quantity before the tax
Answer:
Equilibrium quantity before the tax = 40 units
Step-by-step explanation:
Given:
Qd = 240 - 5P
Qs = P
Computation:
Qd = 240 - 5P
P = 48 + Qd/5
Equilibrium quantity before the tax
Qd = 240 - 5P
P = 240 - 5P
6p = 240
p = 40
Qd = 240 - 5P
Qd = 240 - 5(40)
Qd = 40
Equilibrium quantity before the tax = 40 units

Which table contains only corresponding x-values and y-values where the value of y is one more than the product of x and 2?
Answer:
Option (C)
Step-by-step explanation:
Value of y is more than the product of x and 2.
Equation representing the given condition will be,
y = 2x + 1
Therefore, by substituting the values of x in the equation we can get the table for the input - output values for the equation,
x 0 1 2 3 4
y 1 3 5 7 9
Therefore, table given in the Option (C) will be the correct option.

1. How many pounds of Brazilian Coffee should be mixed with 6 pounds of Colombian Coffee to get
mixture?
Answer:
12 pounds
Step-by-step explanation:
Colombian Coffee sells for $9.25 per pound. Brazilian Coffee sells for $7.75 per pound.
The management wishes to mix 6 pounds of Colombian Coffee with an amount of Brazilian Coffee so that the mixture sells for $8.25 per pound.
Hence:
Let the number of pounds of Brazilian coffee be represented by = a
$9.25× 6 + $7.75 × a= $8.25 (a + 6)
55.5 + 7.75a = 8.25a + 49.5
Collect like terms
8.25a - 7.75a = 55.5 - 49.5
0.5a = 6
a = 6/0.5
a = 12 pounds
Therefore, 12 pounds of Brazilian Coffee should be mixed with 6 pounds of Columbian nuts

The triangles do not meet the criteria of any postulate, therefore, they might not be congruent.
What are Congruent Triangles?There are criteria that can be used to show that two triangles are congruent to each other. They are:
ASA postulate: This says that two triangles are congruent if they have two pairs of congruent angles and one pair of included congruent sides.SAS postulate: This says that two triangles are congruent is they have two pairs of congruent sides and one pair of included congruent angles.HL postulate: If both triangles have equal hypotenuses and a pair of congruent corresponding legs, then they are congruent triangles based on this postulate.SSS postulate: both triangles are congruent if they have three pairs of congruent sides.However, two triangles can have three pairs of congruent angles and may not necessary be congruent triangles.
The triangles in the image below shows that the two triangles have three pairs of corresponding congruent angles. This information is not enough to prove they are congruent.
